The Global Earthquake Model (GEM) Foundation took part in the Taiwan–Japan–New Zealand Seismic Hazard Assessment Workshop, held on 10–11 November 2025 in Yilan, Taiwan. The annual meeting brought together experts from the Taiwan Earthquake Model (TEM), Earthquake Science New Zealand (ESNZ), and Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED), along with international partners, to review recent progress in seismic hazard science across island arc regions.

Discussions focused on advances in seismic source characterisation, site amplification and ground-motion modelling, supporting ongoing efforts to update national seismic hazard models. The workshop provided a forum for technical exchange on shared challenges in modelling complex tectonic environments and for comparing methodological approaches across regions.

GEM was represented by Richard Styron, Senior Active Faults Specialist, who contributed to the programme with a presentation titled “Developing a data-centric workflow for seismic source model construction”. His presentation outlined approaches for structuring and managing fault and seismic source data to support transparent and reproducible hazard model development, with relevance for national seismic hazard updates in island arc settings.

The workshop highlighted the importance of sustained international collaboration in advancing evidence-based seismic hazard assessment and strengthening the scientific foundations that support disaster risk reduction in seismically active regions.

Further details about the workshop and participating institutions are available on the event website.
